Product Description

ABBe 266MST Differential Pressure Transmitter Product Overview
1. Introduction
The ABBee 266MST differential pressure transmitter represents a pinnacle of innovation in industrial measurement technology. Designed for high-performance applications, it integrates multisensor technology to simultaneously measure differential pressure, absolute pressure, and temperature, ensuring exceptional accuracy and reliability in harsh environments. This device is ideal for monitoring liquid, gas, or steam flow, as well as level, pressure, and density in processes with working pressures up to 41 MPa (5945 psi). Its advanced design meets the stringent demands of industries such as oil and gas, chemical processing, power generation, and pharmaceuticals.
2. Key Features
2.1 Multisensor Technology
The 266MST combines multiple sensor systems within a single device:
Differential Pressure Sensor: Measures pressure differences with a span range of 0.05 to 10,000 kPa (0.2 inH₂o to 1450 psi).
Absolute Pressure Sensor: Provides static pressure compensation to eliminate environmental effects, enhancing measurement stability.
Temperature Compensation: Built-in temperature sensors ensure accuracy across varying thermal conditions.
2.2 High Precision and Stability
Base Accuracy: ±0.04% of calibrated span (optional ±0.025% for critical applications).
Long-Term Stability: ≤0.15% of URL (Upper Range Limit) over 10 years, minimizing recalibration needs.
Turndown Ratio: Up to 100:1, allowing flexible adaptation to dynamic process conditions.
2.3 Robust Design for Extreme Conditions
Pressure Resistance: Withstands static pressures up to 41 MPa (5945 psi) and overpressure limits up to 60 MPa (8700 psi) depending on configuration.
Temperature Range: Operates in ambient temperatures from -40°C to +85°C and process temperatures from -40°C to +121°C (silicone oil fill) or -40°C to +85°C (Galden fill).
Environmental Protection: IP67/IP68-rated housing, resistant to dust, moisture, and corrosive substances. Suitable for explosion-proof environments (ATEX/IECEx certified).
2.4 Advanced User Interface
TTG (Through-The-Glass) Technology: Configurable via an LCD display without opening the housing, ensuring safety in hazardous areas.
Plug-and-Play Display: Intuitive interface with a 5-digit numerical readout, bar graphs, and customizable engineering units.
Field-Replaceable Electronics: Modular design allows quick replacement of electronic components, reducing downtime.
